She continued saying: "The doctor put it down to exhaustion and being ill and I actually had this virus and because I didn't have any rest I needed bed rest.

"So I had a couple of days bed rest and I was like 'right I really don't feel well still, something's off' so I went to my own doctor and he said 'you've had this virus you need to have one to two weeks bed rest'".

Katie asked the doctor if she could make a cameo in the show as she hated having time off, but she was told she needed to rest.
